BCH4U Name alkyl group = hydrocarbon chain (2.9-CH3 or -CH2CH3) Date Alcohols Contain the hydroxyl (-OH) functional group NAMING ALCOHOLS a) Find the longest chain of carbons containing the -OH group Attach -ol to the ending of the parent alkane name Number the carbon(s) with an attached-OH group, if necessary (number the parent chain so that the C with the -OH group has the lowest possible number) Use-diol to indicate the presence of 2-OH groups and triol to indicate the presence of 3-OH groups Examples: CH3-CH2-OH ethanol propan-2-01 b) Common names. OH or 160 propanol Isopropyl alcohol d) OH C ㅇ) common name: OH OH 1 CH2-CH2 ethylene glycol (antifreeze) 1,2-ethandiol ethan-1,2-diol OR CH3-CH-CH₃ or 2-propanol phenol If the carbon atom to which the -OH group is attached is also attached to: Secondary alcohol ii) two alkyl groups - OH CH3-CH2 ethanol i) one alkyl group -primary alcohol iii) three alkyl groups -¿tertiary alcohol PRACTICE: a) OH CH-CH-CH2-CH-CH-CH3 GH GH3 CH2643 b) OH 1 CH3 OH H-C-CH2CH3 CH3 2-butanol CH3-C-CH3 2-methyl-2-butanol 4,5-dimethyl-2-hexanol OR 4,5-dimethylhexan-2-01 CH2-CH 2-ethyl-3-methyl cyclopropanol
